在这项研究中，我们检查了一组被诊断为自闭症儿童的弟弟妹妹（婴儿兄弟姐妹）的早期运动、声音和交流发育。从 5 到 14 个月，每个月都会对婴儿兄弟姐妹和无风险比较晚出生的婴儿与主要照顾者在家中进行录像，并在 18 个月时进行随访。作为一个群体，婴儿兄弟姐妹的早期发育里程碑的出现延迟，并且花在更多姿势上的时间显着减少，这表明相对的姿势不稳定。此外，他们还发现，在重复的牙牙学语开始时，手臂节律性活动的变化模式有所减弱。他们很可能在 18 个月大时表现出语言发展迟缓。
In this study we examined early motor, vocal, and communicative development in a group of younger siblings of children diagnosed with autism (Infant Siblings). Infant Siblings and no-risk comparison later-born infants were videotaped at home with a primary caregiver each month from 5 to 14 months, with follow-up at 18 months. As a group, Infant Siblings were delayed in the onset of early developmental milestones and spent significantly less time in a greater number of postures, suggestive of relative postural instability. In addition, they demonstrated attenuated patterns of change in rhythmic arm activity around the time of reduplicated babble onset; and they were highly likely to exhibit delayed language development at 18 months.
